Leaked trophies hint at Batman: Arkham City campaign DLC

Since Batman: Arkham City's release last year, we've seen numerous DLC add-ons including challenge maps, new skins for Batman, and a chance to play as some other characters. But for the first time, we have some DLC that could potentially expand on the campaign.

PS3Trophies have leaked some new trophies which suggest a Harley Quinn themed mini-campaign that lets players take control of Robin. As opposed to previous DLC's which are usually another set of Challenge Rooms, this add-on looks to be an extension of the campaign. It's unconfirmed as to who will be playable in this DLC, but one of the Trophies tasks players with using "5 different Quickfire gadgets in one fight as Robin," leading us to believe we will be playing as the sidekick as some point.
